Match the effects on the concentration of SO2 gas when the following changes occur after initial equilibrium has been established in this system (N. C = no change).
2SO2(g) + O2(g) 2SO3(g) + 46.8 kcal
pressure increases
increase [02]
increase volume of chamber
adding a catalyst
raising the temperature

gas

explanation:

smoke is the matter of a gas

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but

it is reliable if two scientists recorded it

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
